WORLDING AMERICA researches how ‘play’ has been a key force in the past and present process of creating America as a coherent and hegemonic ‘world,’ from 1503 to the present.

The NWO-funded Vidi project “American foreign policy and liberalism” challenges the idea that the United States has created and sustained a “liberal international order” since World War II. It instead explores the ways in which illiberal ideologies – such as those underpinning racial hierarchy at home…

Managing Diversity: Supervising Functions in Managing Colonial Workplaces

Knowledge and culture subproject 1:

The distinction of outstanding and rewarded scientific and educational achievements is an important component of the promotion of our work at the LACDR.

What does the excavated material tell us about the continuation and/or change of urban life during the transitional phrases from Antiquity to the Middle Ages on Crete and in the eastern Mediterranean more generally?

What follows is a survey of existing programs and current projects for each of the participating universities.

Over the past century, the world population has grown exponentially, as has our need for energy and raw materials. If we wish to continue to live prosperously in the future, we have to radically restructure our economy and consumption. Scientific research shows us how to do this.

The nanoscale structure of a catalyst under reaction conditions determines its activity, selectivity, and stability. For the production of sustainable energy and materials, new catalysts are needed. By understanding the structure-activity relationships of catalysts under reaction conditions, insight…

An Investigation into the role of copper-alloy craft production in the early medieval economy of northwest Europe.

Do you have a project that will benefit from analytical skills or knowledge of science and business? Do you want to tap into talented graduate students and test-drive potential employees? Are you looking for temporary management support? Do you want to offer motivated science students the opportunity…

Through metabolism, biochemical processes give rise to the complexity of life. Acquired and inborn errors in metabolism underlie many diseases occurring in man. The challenge for present day medical biochemistry is to find, and integrate, pieces of information at molecular, cell and organismal level…
